Fix intermittent mDNS resolution failures

Browse source 
Switch NetworkManager WiFi backend to iwd to resolve repeated
wpa_supplicant disconnects caused by nl80211 send_event_marker
incompatibility with iwlwifi. Each disconnect was triggering avahi
SIGHUP reloads, causing .local name resolution to fail for several
minutes at a time.

Also disable WiFi power save in TLP and enable IPv6 mDNS resolution
via NSS (nssmdns6) for hosts that only advertise IPv6 addresses.
